Dust Deputy DIY Anti-Static Retrofit Cyclone Separator for Wet/Dry Shop Vacuums (DD DIY)

Great unit, but do your research first. Do not buy the smaller DD unit if you're planning on using it with a 2.5" hose. Overpowering the smaller unit with a larger 2.5" hose vacuum will cause it to be less efficient. Get the 2.5 version; it does a great job with the bigger powered vacuums. I have a 16-gallon Ridgit vacuum, and it works great. If you have the newer Ridgit with the locking hoses, it fits, maybe. The locking part does get in the way of a snug fit. You can cut the locking part of the hose off, or do as I did and just wrap a single turn of black tape around the hose end, and it works great. Later, I got the Ridgit 20-foot extension hose, and it came with adapters that don't have the locking tab and fit perfectly. Also allowed me to keep the vacuum in one place and vacuum 20 feet in any direction. I connected my hose to one of my blast gates that fits perfectly. Some complaints about not getting the really fine dust are true to a point. First, not buying the right DD for your vacuum will cause more fine dust to go into your vacuum and not the DD system. The 2.5 DD works great for me with very little fines getting into my vacuum itself. I also use a filter bag in my vacuum to catch any fine particles that do get by, to save the cost of the expensive filters. Also, easy clean up. I used this setup to clean enough sawdust in my shop to fill a 30-gallon barrel, and the dust bag in the vacuum still barely has anything in it with no noticeable loss of suction. Some complain of units toppling over and breaking. Well, use some common sense here people. If you want this to be mobile, you need to weigh it down or widen the base or secure it to the vacuum, as some have done, so it doesn't topple over. See YouTube for many ideas. I did my home shop in 2" PVC. Why, because if you notice the inside of your 2.5" vacuum hose is closer to the 2" dia. and has ridges on the interior causing friction, reducing suction, so why not use 2" smooth PVC piping. Plus PVC can be heated with a heat gun and made to fit just about any size dia. you may need. Works great with my PowerTec blast gates with no adapters. Heated a 2" PVC wye end and pressed the PowerTec into the wye. Good to go. I used metal duct tape to seal the joints air-tight with no gluing needed, so that I can change my setup anytime, if needed. Bottom line, this is a great system for a HOME shop and does have some drawbacks. Cheap material, maybe, but there have been no problems on this end. Don't drop it or bang it; it's not made of metal. Oneida does make metal ones at a much higher cost and is a leader in the industry on this type of dust collector. These are made at a much lower cost for the homeowner in mind. DO YOUR RESEARCH on what you're trying to accomplish in your shop. My set-up: Ridgit 16-gallon NXT, Oneida 2.5 DD, 15 feet 2" PVC with eight wye fittings, eight 2" PowerTec blast gates, BAYISAM 2-1/2"x20'Dust Collection Hose(Black Wire) to connect all my tools to 2.5" adapters. My sanders are at the end of the line and still work great at dust colection.

The Oneida Dust Deputy 2.5 XL is a game‑changer for shop cleanup. Its cyclone design captures nearly all dust and debris before it reaches the vacuum, keeping filters clean and extending suction power. The high CFM capacity makes it perfect for larger wet/dry vacs, and it handles heavy shop use without clogging. Setup was straightforward, and once connected, it immediately improved efficiency. I can run my CNC, sander, and planer without worrying about constant filter changes. The build quality is solid, and the performance is consistent across different materials—wood chips, fine dust, even heavier debris. Overall, this separator delivers durability, efficiency, and serious dust control. It’s one of those upgrades that pays for itself quickly in saved time and cleaner air.

I've got to say that I was skeptical at first with this thing, but after just one use I am thoroughly impressed. At $50+ the price is steep for just the cyclone piece, I think they could throw in a gasket, or maybe some various hose adapters. I'm using mine on a white "food grade" 5 gal bucket I bought from Home Depot. A quick squeeze of this bucket compared to the typical orange Homer bucket revealed the white one was a tad thicker and I thought would be better at not squeezing in. I made a rigid round doughnut for the lid about 9 inch diameter and and caulked it to the lid. I also printed out Oneida's template for the bolt pattern. I got a 1/8 inch thick 6" x 6" piece of rubber from Ace Hardware to make a gasket seal between the cyclone and the top of the lit. I used 1/4inch x 1 1/2 long bolts with washers and nuts to attach it. Came out looking sweet and feeling really solid. Attached to the bucket and gave it a whirl. Only minor lid depressions from the suction, and no leaks. Like other people complained, it is a little tippy. But I'll resolve that with some concoction of a cart to hold the vacuum too. I don't do a ton of woodworking, so I feel the 5 gal bucket size will be fine for my need. As far as the vacuum, I'm using a Home Depot Rigid model WD4070 bought for $69. I looked around for the something that sucked but didn't suck* and thought that was the best value. I am very happy with the power, size, and abilities of it. It's not as loud as people complain too. I felt that since I was using the dust deputy, I didn't need a huge shop vac, so I opted for a similar power one with a smaller volume. Not sure about the science behind all the static pressure, and suction pressure. But this one gets the job done well. After a 20 minute run sucking up saw dust of poplar, pine, and fir, and some plane shavings, the dust deputy did incredible. Its satisfying seeing it swirling around in there too, and even more satisfying when I opened the vacuum up after and not a freakin spec of saw dust was found. Its almost like magic! haha. The only frustrating occurrences I had were with the hoses, attachments, and adapters. Since I can't really blame Oneida for that since they didn't provide any, and it would be hard for them to because of all the different sizes out there. The adapter and hose companies really ought to dumb it down for us DIYers, and color code which hose will fit on which connections. The outer diameter and inner diameter sizes are a nightmare, and it really forces you to over-buy several different options bring it home and see what fits, then return what doesn't. The good thing about the dust deputy is [that I thought at the time] that the nozzles are tapered so maybe it could fit a few different close sizes. I ended up buying a larger hose for the vacuum end, and using the original hose that came with the vac, on the opposite end before the dust deputy. Ugh. My local HD didn't have a big selection of adapters, nor did they have optimal size rubber-and-hose-clamp ones. PROs: would buy it again, well engineered and gets the job done well. Con's: prepare for an annoying time getting hose fittings to work.

Alv si funciona, increíble como algo tan simple puede dar solución a un problema. Recoge perfecto el aserrín y el polvo, incluso pelos de mis mascotas. Solo le hice unos adaptadores con mi impresora 3d para usarlo con mi aspiradora truper y listo. Pasa muy muy poco polvo a la aspiradora, menos gasto en filtros qué son carisimos.

Do not buy this unless you have the perfect bucket for it

Excelente

Werkt geweldig. Ik gebruik hem met de bosch gas 15 ps en de zuigkracht blijft goed ondanks het gebruik van 2 slangen. Ik moest vroeger mijn stofzuiger met moeite schoonmaken en uitkloppen, daarnaast verloor ik snel zuigkracht. Met de Oneida zijn dat geen problemen meer. Ik heb er een metalen olievat onder geplaatst om de stof op te vangen. Dit is een must have als je een bouwstofzuiger hebt!

Yet to be installed but very happy with the purchase and perfect for my needs.
